Introduction
FLH211、FLH311、FLH310
Natural quartz ingot made by flame fusion process, less bubble, high transparency and good geometry , optimum rate of utilization.
FLH321、FLH320
High purity natural quartz ingot ,made by flame fusion process, less bubble , high transparency and good geometry , optimum rate of utilization.
FLH321H、FLH320H
High purity natural quartz ingot with lower aluminum、low alkali metal elements.
FLH321HS
Almost bubble free, ultra-high purity, low alkali and low aluminum, almost no wrapping, strong high temperature resistance, it is an ideal window material.
FLH321N、FLH320N
Norwegian sand material , made by flame fusion process, less bubble, high transparency and good geometry , optimum rate of utilization.
The material has few bubble in it with excellent transparency and geometric dimension .They are widely used for semiconductor,Optical Fiber, Solar Energy Photovoltaics, Optical Coating/Filming.
Thanks to the few bubbles, high purity, almost no inclusion, high temperature resistant performance and other characteristics,FLH321HS has been widely used in semiconductor advanced manufacturing, optical, chemical processing, UV and high temperature window.
